Lose all power to electrical system when I dim my headlights
This happens intermittently. While driving at night I dimmed my headlights and all my interior lights, radio, dash lights ,gauges, and headlights turn off for a few seconds then come back on. The truck stays running. What would cause this?
There are several possibilities; loose or corroded battery cable connection - be sure the check both ends of each; the positive and negative (ground) cable; loose wiring harness connection(s) under the instrument panel, or under the hood; faulty fuse or breaker connection; faulty body control module or it's associated wiring.
